VEHICLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 431,873, dated July 8, 1890.

Application filed May 23, 1890. Serial No. 352,953. (No model.)

To @ZZ whom it may concern.-

Be it known that I, ELIsHA CRAWFORD BUTT, a citizen of the United States, residing at Portland, in the county of Sumner and State oi Tennessee, have invented a new and useful Automatic Vehicle-Brake, of which the following is a specification.

The invention relates to improvements in automatic vehicle-brakes.

The object ot' the present invention is to provide a simple and inexpensive automatic wagon-brake adapted to be readily operated bythe animals and capable of having its operation suspended when it is desired to back the vehicle. l

The invent-ion consists in the construction and novel combination and arrangement ot' parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective View of a running-gear provided with an automatic brake constructed in accordance with this invention. Fig. 2 is a reversed plan View. Fig. 3 is a central vertical longitudinal sectional view.

Referring to the accompanying drawings, 1 designatesa tongue capable of limiting longitudinal movement between front hounds 2, which are secured in the ordinary manner to a front axle 3, and have their rear ends connected by a cross-bar 4,which is set into the hounds, and has its upper face flush with the upper faces of the ends of the hounds, and it formsa bearing upon which the reach 5 slides. The reach 5 is pivoted to the front axle and has the rear hounds 6 and the rear axle 7 adjustably secured to it in the usual manner. The rear end of thetongue l is provided with a plate 8, that is hinged to a slide 9 by a removable pintle 10, that is adapted to be Withdrawn from the eyes of the plate and the slide to permit the tongue to be withdrawn and removed from the front hound 2, which have their forward ends connected by plates 1l and l2, which are arranged, respectively, on the top and bottom of the hound, and form with the latter a way in which the tongue slides, and the upper plate ll is provided with an integral centrally-arranged bracket 13, which has a rearward-projecting horizontal arm la, between which and the plate is pivoted a doubletree l5, having singletrees secured to its ends in any preferred manner. The slide 9, which is hinged to the tongue, passes through a recess 1G of a spring-bar 17, and the mouth of the recess is closed by a plate 18, upon the upper face of which the slide bears, and the latter is provided with a longitudinal slot 19, in which the king-bolt 20 is arranged. The rear end of the slide is provided with an eye or loop 2l,in which .are pivoted the inner adjacent ends of brake-levers 22, which are fulcrumed upon the rear ends of the hounds, and are provided at their outer ends upon the sides adjacent to the front wheel with brake-shoes 23, that are adapted to be brought into engagement with the front wheel when the tongue is moved rearward by backing the animals. The inner adjacent ends 2G of the levers 22 are provided with slots 24, through which the pivots 25 pass, that secure the levers in the eye or loop, and the levers 22 are provided on their lower faces with lugs 27, through which the pivots 28 pass, that fulcrum the levers on the hounds, and the said lugs raise the levers above the hounds and provide between them and the rear cross-bar 4 a space, in which the reach 5 can freely move.

The outer ends of the brake-levers are provided with step-brackets 29, and in order to brace the parts a bar 30 is provided and has its ends secured to the hounds 2 about midway between the front axle and the brake-levers, and has secured to it intermediate of its ends a strap 3l, whichis arranged above and spans a recess 32 to receive the slide.

The brake, when the tongue-chains are slackened, is held out of engagement with the wheels by a spring 33, secured intermediate .of its ends to the lower face of the rear end of the tongue and having its ends loosely engaging the front axle and guided and retained in proper position by keepers 34.

By hinging the rear end of the tongue to the slide the brake-levers and shoes and the adjacent parts will not be cramped should the tongue be forced upward, and the removable pintle enables the tongue and the slide to be readily separated and removed.

Then it is desired to back the wagon, the

tongue is held stationary by a pin 35, which passes through registering perforations 36 and 37 of the top and bottom plates and the tongue, and when the pin is not in use it is placed in a perforation 38 at the side ot` the top and bottom plate.

From the foregoing description and the accompanying drawings the construction, operation, and advantages of the invention will be readily understood.

What I claim isl. The combination of the front hounds suitably secured to a front axle and having their rear ends connected by a cross-bar 4 and their front ends by top and bottom plates, the tongue capable of limited longitudinal movement between. the hounds and provided at its rear end with a plate 8, the slide having at its rear end the loop 25, the removable pintle hinging the front end ot` the slide to the plate of the tongue, the brake-levers fulcrumed to the rear of the hounds and provided with lugs on their lower faces to raise the levers above the cross-bar 4c to provide a space for the reach, said brake-levers having ing their adjacent ends slotted and pivoted in the eye or loop of the slide, and the spring having its ends loosely engaging the front aXle and secured intermediate of its ends to the rear endl of the tongue, substantially as described.

2. The combination of the axle, the hounds secured to the aXle and having their rear ends connected by a cross-bar 4 and their front ends provided with a bottoni plate 12 and a-top plate Il, having an integral bracket 13, with a rearwardly-extending arm 14, the tongue capable ot longitudinal movement between the hounds and provided at its rear end with the slide hinged to the plate of the tongue and provided at its rear end with a loop or eye, the brake-levers fulcrumed on the rear ends ot the hounds and pivoted in the eye or loop of the slide, the brace 30, secured to the hounds between the axle and provided with a recess, the strap 3l, secured to the brace and spanning the recess, and the spring secured to the tongue and having its free ends bearing against the front axle and arranged in keepers, substantially as described.

3. The combination of the front hounds, the tongue capable of limited longitudinal movement between the hounds and provided at its rear end with a plate 8, the slide having at its rear end the loop 25, the pintle hinging the front end of the slide to the plate of the tongue, the brake-levers fulcru med to the rear of the hounds, said brake-levers having their adjacent ends slotted and pivoted in the eye or loop of the slide, and the spring having its ends loosely engaging the front axle and secured intermediate of its ends to the rear end of the tongue, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
